The present disclosure provides a method, an apparatus, a storage medium, and an electronic device for controlling an IoT device. The method includes: receiving detection data reported by an IoT device; verifying device control information based on the detection data; and sending, in response to second data in the device control information being successfully verified, a control instruction configured for execution of a pending action to the IoT device to be controlled based on first data. The above method is conductive to improving the response speed of the IoT device.

Method, apparatus, storage medium, and electronic device for controlling IoT device

The present invention provides a hydrogenation catalyst, containing a carrier, metal components of nickel, molybdenum and tungsten supported thereon, and an adjuvant component selected from the group consisting of fluorine and phosphor and combination thereof. In another embodiment, the present invention provides a hydrogenation catalyst, containing a carrier and metal components of nickel, molybdenum and tungsten supported thereon, wherein said carrier contains a molecular sieve. The present invention provides further use of said catalyst in the process for hydrogenating hydrocarbon oil. In comparison with a hydrogenation catalyst according to the prior art, the catalyst according to the present invention has a much higher activity.

Hydrogenation catalyst and use thereof

A presulfurization method of hydrogenation catalyst comprises mixing an olefin-containing component, elemental sulfur and a promoter, heating the resultant mixture at 100-120&deg; C. for more than 0.5 hours, wherein the mole number of elemental sulfur is at least not less than that of double bonds of the olefin, and the amount of the promoter used is 10-80% weight of the amount used of elemental sulfur, and said promoter is selected from an organic promoter used usually in rubber curing; the elemental sulfur-incorporated catalyst is impregnated with the product obtained, and heated at 100-300&deg; C. in an inert atmosphere for more than 1 hour; wherein the volume amount of said product used is at least 60% of the pore volume of the catalyst. In the case of a little amount of the promoter being used, the presulfurization method can improve greatly the sulfur retention degree of the catalyst.

Presulfurization method of hydrogenation catalyst

The present invention discloses a hydrofining catalyst. The catalyst has the following composition based on the total weight of the entire catalyst composition: 1-5%(wt.) nickel oxide, 12-35% (wt.) tungsten oxide, 1-9% (wt.) fluorine, and the balancing amount of composite alumina. Said composite alumina is composed of one or several kinds of micropore alumina and one or several kinds of macropore alumina, wherein the weight ratio of micropore alumina to macropore alumina is 75:25 to 50:50. The term 'micropore alumina' in the context means the alumina in which the volume of the proe of diameter less than 80 angstrom occupies more than 95% of its total pore volume, while the term 'macropore alumina' in the contest means the alumina in which the volume of the pore of diameter 60-600 angstrom occupies more than 70% of its total pore volume. The pore distribution mentioned above is determined by BET method of nitrogen adsorption at low temperature. This catalyst is especially suitable for the hydrofining of inferior distillates with high sulfur content and boiling range of 80-550.degree. C.
